Predictive Discovery Limited ( ASX: PDI ) announces that assays have been received from infill and extension RC drilling on the Tambiri and Solna Prospects in the Bangaba Project in eastern Burkina Faso.
Managing Director’s Assessment of Drill Results
Mr Paul Roberts, PDI’s Managing Director commented: “ These new RC drilling results confirm that Solna is an intrinsically high grade gold deposit and have clarified our understanding of the geology of both Solna and Tambiri. At Tambiri, the broad gold intercepts at both the northern margin and the southern end point to additional mineral potential in both directions. These encouraging results move us significantly closer to a maiden JORC Resource at Bangaba in the next 6 months.
Previously we announced that more than 8km of gold in bedrock geochemical anomalies have been identified at Bangaba, mostly along strike from Solna and Tambiri. Most of these remain untested and indicate significant gold potential within the Bangaba Project outside of the Solna and Tambiri Prospects.”
Bangaba Project Background
The Bangaba project in Eastern Burkina Faso (Figure 1) covers areas of extensive artisanal mining. PDI is earning a 95% interest in the 128 km[2] Bangaba exploration permit by making a series of staged payments in cash and shares. PDI’s equity now stands at 68%.
It is estimated that artisanal miners have produced several tonnes of gold at Bangaba over 27 years. Artisanal workings are located on two complex structures on the north‐west and south‐east contacts of a granodiorite‐diorite body (Figure 2).
Previous RC and diamond drilling programs at the two major sites of artisanal mining, Solna and Tambiri, have generated a series of high grade intercepts, including: 2m at 56g/t Au , 5m at 17g/t Au , 7m at 13g/t Au , 9.3m at 4.9g/t Au and 5.6m at 16g/t Au .
This release summarises assay results from a 6,584m RC drilling program completed in April‐May 2012.
RC Drilling Program

==> picture [596 x 80] intentionally omitted <==
This RC drill program was designed primarily to infill or test extensions of the known mineralisation at Solna and Tambiri, and resulted in gold intersection spacings of between 40 and 80m. Results from all the holes drilled are tabulated at the end of this release.
Tambiri (Figure 3)
At Tambiri, better intercepts included:
-
20m at 2.3g/t Au from 48m including 1m at 15g/t Au ‐ northern extension
-
20m at 2.2g/t Au from 138m including 4m at 7.0g/t Au – southern extension
-
12m at 1.7g/t Au from 88m
-
12m at 1.4g/t Au from 96m
-
12m at 1.4g/t Au from 108m
The Tambiri Prospect is an open pit target with underground potential. These drill results largely confirmed the earlier geological interpretation except that the two 20m intercepts listed above extended the outline of thicker gold intercepts both to the north and south (Figure 3). The northern intercept was approximately 40m below surface and the southern intercept was about 130m below surface, indicating an overall shallow southward plunge. Mineralisation remains open to the north and south.
The Tambiri gold mineralisation is also open at depth directly beneath the zone of higher grade intercepts (pink shaded area on Figure 4). Several holes in this area steepened more than was anticipated with the result that one hole stopped in low grade mineralisation and a second hole may have failed to reach the lode position.
The gold mineralisation dips steeply to the south‐east and all intercepts correlate clearly within a gold‐bearing quartz vein system that is typically between 5 and 20m thick.
Solna (Figure 4)
At Solna, better drill hole intercepts included:
-
2m at 20.4g/t Au from 70m including 1m at 40g/t Au
-
4m at 8.0g/t Au from 194m including 1m at 29g/t Au
-
5m at 5.7g/t Au from 39m including 1m at 12g/t Au
-
2m at 10g/t Au from 134m including 1m at 19g/t Au
-
2m at 10g/t Au from 51m
The Solna Prospect is targeted as an open pit and underground gold deposit. A revised interpretation based on the new results (Figure 4) suggests a simpler interpretation than previously understood. The bulk of the gold mineralisation is located within the “B Lode” which
==> picture [596 x 60] intentionally omitted <==
----- Start of picture text -----

----- End of picture text -----
==> picture [596 x 80] intentionally omitted <==
generally dips to the south‐east at an angle of approximately 50 degrees. A higher grade zone (e.g. 5.6m at 16g/t Au , 7m at 13 g/t Au , 4m at 8g/t Au , 2m at 10g/t Au ) appears to plunge shallowly towards the east (see Figure 4). These grades and widths are likely to support underground mining and warrant follow‐up because mineralisation remains open at depth.
South of the B Lode, two other lodes are identified, both with high grade cores which peak at 2m at 56g/t Au (“A Lode”) and 6m at 20g/t Au (“D Lode”). The second intercept is an upgraded value resulting from recent analysis of 1m samples taken from the previously reported 2m composites; it includes a single metre interval of 1m at 111g/t Au . Both lodes are open at depth.
Drilling in the recent program targeted at the northern extension of the “C Lode” (Figure 4) did not intersect high grade mineralisation, however the recent geological re‐interpretation suggests that this lode may trend in a different orientation towards the north‐east and therefore has not yet been effectively tested.
Outlook
The current drilling program has clarified the geological interpretation at both Solna and Tambiri to enable preparation of a JORC Resource calculation. Some additional drilling will be required to achieve this over the full extent of the mineralisation identified to date, and this is planned for October‐November 2012. Drill testing of the new extensions at Tambiri and Solna may also be carried out at the same time.
A preliminary program of metallurgical testwork on samples from both Solna and Tambiri is also planned over the coming months.

PDI has a distinctive technological capability, known as Predictore [TM] , which is designed to increase drill targeting efficiency thereby reducing ore discovery cost. The Company’s major focus is in Burkina Faso, West Africa where it has assembled a substantial regional ground position totalling 1,544km[2] and is exploring for large open‐pittable gold ore deposits.
Competent Persons Statement
The exploration results reported herein, insofar as they relate to mineralisation, are based on information compiled by Mr Paul Roberts (Fellow of the Australian Institute of Geoscientists). Mr Roberts is a full time employee of the company and has sufficient experience relevant to the style of mineralisation and type of deposits being considered to qualify as a Competent Person as defined by the 2004 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the JORC Code, 2004 Edition). Mr Roberts consents to the inclusion in the report of the matters based on his information in the form and context in which it appears.
